I have a 13-inch, 2018, Four Thunderbolt 3 Ports MacBook Pro. For me, in compressor, keeping all other settings the same, it takes about ten times longer to export using HEVC versus H264. Is that normal ?
Edit : 8bit HEVC
MacBook Pro 13”, macOS 10.15
Oh wow yes, so I tested again on two clips. The encoder type setting makes all the difference in time to export.
Here are the results for one of the clips.
3min29sec clip 1280x720p :
H264 file size is 30% smaller than HEVC fast, though. Quality seems about the same from the two clips.
HEVC slow file size is exactly the same as H264, but quality is very noticeably better.
So.... in the end... I know which setting I want to use (HEVC with slow encoder type for better quality at smaller file size), but I know it takes forever (20x longer than HEVC slow)... 😅

OhOhOh actually by telling you about the encoder type, which I hadn't paid attention to before, just leaving it as the default, I wanted to check it out ! And in fact, by using the faster type, it seems to improve by a lot ! I'm gonna check more into it and get back here to share the results !
No, it's not a preset anymore. I used the Youtube 4K as a base for H264, but then changed some things.
And then, from this H264 preset I juste made a copy and changed only H264 to HEVC without changing anything else. But this defaults to 8 bit HEVC with slow encoder type as described above.
EDIT : added clear answer - no, but...
10-bit or 8-bit?
Oh yes sorry 😅 8-bit... And it's using the encoder type - slower for better quality. (Sorry if wording is not exact as I'm using compressor in French)
I'm very surprised you're seeing that big a difference. On my machine HEVC 8-bit in Apple Devices is actually a bit faster than H. 264 Apple Devices best quality for the same file.
Are you using Apple presets? Which ones? Not seeing quality presets for HEVC, just 8-bit or 10-bit.
HEVC takes 10x more time to export than H264
